The 2018 Global DNS Performance Report measures the performance of three DNS infrastructures-managed DNS providers, public resolvers, and global roots. It’s designed to provide data to enterprises and software as a service (SaaS) providers on infrastructure that’s critical to digital experience. It provides a point-in-time study of performance that can be used to make provider choices and track changes over time. The report also includes findings on the state of DNS deployment among enterprise and SaaS providers.
